How to solve the temperature rise problem of explosion-proof vibration motors

With the increase of the degree of mechanization of coal mining, explosion-proof vibration motors not only put forward high requirements on the performance of the motors, but also put forward higher requirements on the quality and reliability of the vibration motors. Excessive temperature rise of the motors restricts the explosion-proof vibration motors An important factor in development, so controlling the temperature rise of flameproof vibration motors has become an urgent problem. Compared with ordinary vibration motors, explosion-proof vibration motors have extremely important special characteristics.

Let's analyze them one by one for everyone:

1. Explosion-proof vibration motors must not be disassembled at will; when disassembling and overhauling, the explosion-proof surface of the parts cannot be used as the fulcrum of the crowbar, and it is not allowed to knock or hit the explosion-proof surface.

2. When disassembling the motor, first remove the air hood and fan, and then remove the bolts of the end cover and bearing cover with a sleeve wrench. Then, use a log or copper rod to hit the shaft extension in the axial direction to separate the end cover and the base. And finally remove the rotor. When removing parts, place the explosion-proof side up and cover them with rubber or cloth pads. Be careful not to lose the bolts, spring pads, etc.

3. When dipping and assembling, the insulation paint or dirt attached to the explosion-proof surface should be cleaned. Do not scratch with hard objects such as iron plates, but you can grind uneven places with oil stone. To prevent the explosion-proof surface from rusting, apply engine oil or 204-1 replacement type anti-rust oil to the explosion-proof surface.

4. If the explosion-proof surface is damaged, you must use lead-tin solder HISnPb58-2. The flux is 30% hydrochloric acid (for steel parts) or tin-zinc solder containing 58 ~ 60% tin. The flux is 30% ammonium chloride. Chlorine Zinc 70%, water 100 ~ 150% mixed solution (for cast iron parts) for welding repair, the combination of solder and parts must be firm, the convex part must be smoothed to achieve the specified finish.
